CLAMP FOR HOLDINGVFRUIT-JARS.

SPECIFICATION forming part of Letters Patent No. 354,705, dated December21, 1886.v

Application filed September 4, 1886. Serial No. 21%,721. (No model.)

.To all whom it may concern:

Be it known that I, THEODORE KENDER- DINE, a citizen of the UnitedStates of America, residing at Lisbon, in the county of Linn and Stateof Iowa, have invented a new and useful Clamp for Holding Fruit-Jars andSimilarArticles, of which'thefollowing is a specification.

My invention has relation to improvements in means for holdingfruit-jars while removing the tops.

As is well known, the tops or covers of screw-top fruit-jars often stickso'tight that it is almost impossible to start the top from the jar, andthat the effort made by holding thejar with one hand and the top withthe other hand usually starts the top, with the result of throwing someof the sirup out of the jar and over the person.

Itis the object of my improvement to pro-' vide a' simple and effectivedevice adapted to be clamped to a table or other convenient object, andin which the can or jar may be set and clamped, and the top then screwedofi without danger to the neck-flange, and without spilling thecontents.

My invention consists in a new article of manufacture, as is hereinafterfully described, and especially as the same is pointed outrin the claimmade hereto. t

I have fully illustrated my improved article in the accompanyingdrawings, wherein Figure 1 is a perspective View of the device, and Fig.2 is a plan View thereof.

Reference being had to the drawings, the letter A designates theclamping band or frame. This consists of a metal band bent into somewhatof an angular shape, substantially as shown. A circular shape willeffect 4c the purpose;but I prefer a heptagonal conformation, as shown,because this takes and holds the jar or can with a better grip andagainst turning. On the inner face of the inner end of this frame isscrewed an elastic 4,5 cushion, 1, against which the jar is pushed whenthe clamping-follower is screwed up.

The elasticity or yielding characteristic of this cushion prevents thejar from breaking,

yet holds it sufficiently firm for the purpose 5O intended. In the outerend of this clamping frame is formed a threaded hole, 2, which takes theclamping-screw of the follower.

The letter B designates the clamping-arm, which is of angular shape, asshown, and is either welded on or attached to the clamping- 5 frame byrivets or screws. In the end of this clamping-arm is a threaded hole inwhich is fitted the clamping-screw 3, provided with a thumb wheel orcrank, 4, and having on it a; loose clamping-nut, 5, as usual. This partof the device constitutes the means for holding the frame to the tableor other object; but it will be perceived that the frame serves thedouble function of the upper limb or part of the table-clamp and ofholding the jar through 6 5 the instrumentality of theclamping-follower.

The letter O designates the clamping-screw projected through thethreaded hole in the frame A, and provided with a handle, 6, to turn it.Swiveled on the inner end of the jar-clamping screw is the follower 7,which consists of a curved metal plate having secured thereto an elasticcushion, 8. In practice this follower is held in horizontal positionbythe object to which the device is clamped, and in this position ispushed against the jar or can.

The operation is .as follows: The device is set to the table by placingthe frame over the top of the table with the clamping-screw under, andthen turning the clamping-screw up until clamped tight. The jar is thenplacedwithin the frame and the follower screwed up until clamped tight,when the top may be turned off by the hand, or by any proper appliancemade for that purpose.

What I claim as my invention, and desire to secure by Letters Patent,is-

As an improved article of manufacture, the improved jarclamping deviceherein described, composed of the frame A, provided with an elasticcushion, 1, the angular clamping-arm B, provided with clamping-screw .3,the jar-clamping screw 0, and swiveled follower 7, having elasticcushion 8, all arranged and operatedas set forth.

In witness whereof I have hereunto set my hand in the presence of twoattesting witnesses.

THEODORE KENDERDINE.
